About AGX
A runtime built for agents, not retrofitted from existing tooling
Most sandboxes were built for one developer running one script. The moment your agents need to scale, you hit slow spin-up times and single-user assumptions.
AGX, by contrast, was built for agents from the ground up. Even our hypervisor, Substrate, was purpose built. Critical state lives outside the sandbox and outlives it. AGX also includes features for teams to discover, deploy, and connect agents.

Agentic performance at scale
Agents don't run once. They loop, branch, and retry. Often spinning up a sub-agent and sandbox at nearly every step, and a two-second cold start that's fine for one agent becomes dead time when a fleet does it ten thousand times.
Substrate boots and forks sandboxes up to 10x faster than Firecracker, so agents can branch into parallel attempts, retry instantly, and resume from a snapshot with minimal boot latency. Don't believe us? We published our benchmarks. Take a look.
